SLIDE-BUCKLE.

SPECIFICATION forming part of Letters Patent No. 722,375, dated March 10, 1903 .l

Application filed J' une 23, 1902.

To all wiz/0m t may concern:

Be it known that I, JAMES F. MoLLoY, of Westhaven, in the county of New Haven and Stato of Connecticut, have invented a new and useful Slide-Buckle; and I do hereby declare the following, when taken in connection with the accompanying drawings and the iigures of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent, in-

Figure 1, a view in front elevation of a slide-buckle constructed in accordance with my invention and shown as applied to a piece of suspender-webbing; Fig. 2, a view in vertical section on the line ct b of Fig. 1; Fig. 3, a detached view, in front elevation, of the slide-buckle; Fig. 4, a corresponding edge view thereof; Fig. 5, a view in transverse section on the line c d of Fig. I; Fig. 6, a view corresponding to Fig. 2, but showing the slide having its tongues offset to a greater extent and applied to thicker suspender-webbing.

My invention relates to an improvement in that class of sheet-metal suspender-buckles known as slide-buckles, the object being to produce at a low cost for manufacture a simple, convenient, and effective slide-buckle constructed with particular reference to reducing the thickness of the combined buckle and webbing to the minimum and to adapting the buckle to be adjusted as required to vary the friction upon the webbing, as well as to receiving webbing of different thicknesses. I

With these ends in view my invention consists in a sheet-metal slide-buckle having certain details of construction, as will be hereinafter described, and pointed out in the claims.

In carrying out my invention as herein shown I form two tongues 2 2, so as to extend inwardly in line with and toward each other from the central portions of the end walls of a large rectangular or oblong clearance-opening 3, arranged horizontally in the center of the buckle-body 4, the adjacent ends of the said tongues being separated by a space 2. The said body is also formed with an upper finger-piece extension 5 and a corresponding lower inger-piece extension 6 of loop-like form for the attachment of the usual Serial No. 112,896. (No model.)

finger-pieces or tabs, by means of which the slide is seized for operation. As shown, the

said tongues 2 2 are located in a plane parallel with but back of the plane of the clearanceopening 3 and the body4 of the buckle, and it is apparent thatby suitably bending them at the points Where they merge into the end walls of the said' opening 3 they may be made to stand more or less to the rear of the plane of the said opening 3 and body 4, as desired.

In threading the buckle a loop 7 is formed at one end of the webbing 8 and applied to the tongues 2 2, which are entered into the opposite ends of the loop 7, which is crowded into the space 2? between the said tongues in applying it to the tongues. The other end of the webbing is then carried forward and up under the linger-piece 6 and the lower edge of the body 4 and outward through the lower portion of the clearance-opening 3 and then upward over the outer face of the loop 7, and therefore over the outer faces of the tongues 2 2, and then inward through the upper portion of the clearance-opening 3 and upward under the upper edge of the body 4 and the finger-piece 5. In the upward passage of the webbing over the loop 7 it is so deiiected and so brought into frictional contact therewith that it is gripped so that it will not move in the buckle except when the same is grasped by one hand and the webbing by the other and both pulled in opposite directions.

Under m y im proved construction the thickness of the combined buckle and webbing is reduced to the minimum, as shown in Fig. 2. This is `a point of great advantage, as the thinner the suspender at this point the more comfortable and the less clumsy it is. The amount of friction developed between the loop and the other end of the webbing will obviously depend upon the position of the tongues with reference to the plane of the body of the buckle or the size of'l the clearance-opening, or both. Thisv friction may be very readily regulated in a given buckle by bending the tongues at the points where they merge into the end walls of the clearanceopening. In this way my improved buckleslide may be adapted to thick or thin webbing. As shown in Fig. 6, the tongues 9 of IOO the buckle are set suciently far back from the plane of the body 10 of the buckle to permit the use of a thick 'webbing 11. I would therefore have it understood that I do not limit myself to the exact construction shown, but hold myself at liberty to make such variations therefrom as fairly fall within the spirit and scope of my invention. Thus the tongues might be located in the plane of the buckle and clearance-opening by properly proportioning the same in size.

, Having fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A sheet-metal slide-buckle comprising an oblong body formed with a large longitudinally-arranged oblong clearance-opening, and with two alined tongues extending inwardly toward each other from the end walls of the said opening and separated from each other by a space, and the said body being furnished upon its upper and lower edges with integral extensions for the attachment of iinger-pieces or tabs; in combination with a suspender-webbing one end of which is formed into a loop which is crowded into the said space between the ends of the tongues for the entrance of the tongues into the opposite ends of the said loop, and another portion of which webbing is threaded into the said body by being passed from the rear to the front thereof through the lower portion of the said clearance-opening, and then over the front portion of the said loop and then from the front of the said body to the rear thereof through the upper portion of the said opening, whereby the portion of the webbing so threaded is deflected and maintained in frictional contact with the front portion of the loop.

2. A sheet-metal slide-buckle comprising an oblong body formed with a large longitudinal1y-arranged oblong clearance-opening, and with two alined tongues extending inwardly toward each other from the end walls of the said opening and separated from each other by a space and located in a plane parallel with, but back of the plane of the said body which is furnished upon its upper and lower edges with integral extensions for the attachment of finger-pieces or tabs; in combination with a suspender-webbing one end of which is formed with a loop which is crowded into the said space between the ends of the said tongues which are entered into the opposite ends of the loop, and another portion of which is threaded into the said body by being passed from the rear to the front thereof through the lower portion of the said clearance-opening, and then up over the front portion of the said loop and then from the front of the said body to the rear thereof through the upper portion of the said opening, and then back of the upper portion of the said body, whereby the portion of the webbing so threaded is deflected and maintained in frictional engagement with 'the outer portion of the loop.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses.
